Adding ottos

0

I'm going to be adding 3 ottos to my 20 gallon tall. It well have 10 blood fin tetra and ghost shrimp. I know that I need to wait for the tank to season before adding in the ottos but I'm not sure how long I should wait? I'ts planted with 1 anubias going to 2 more soon, 2 java fern and 2 amazon sword. It's been cycled (still no fish...) for four days. Thanks in advance

I waited a few months to add mine, and acclimated them very very slowly via drip. They're fragile fish.

Also, I'd suggest you start with more than three. They like to be in a school, and you are probably going to lose some in the first months as well. So maybe five. As long as you feed them (mine go crazy over cucumber and nothing else), you should be OK with that number. They have a small bioload - I have both heard that and witnessed it..they aren't that messy. But, you know, keep an eye on your params.

A good sign of a healthy oto is a fat oto. Since they are vegetarians exclusively, they need to be eating a lot to maintain their mass.

Once you start to get algae growing in your tank you know its been long enough. If your water is good enough to prevent algae then just wait a few months after your tank is completely cycled. I would think 3 months would be enough.

wow i disagree with nearly everything..

ottos don't care for schools.
in a 20 gallon i'd say keep 2 because there won't be enough algae to go around which is their preffered food. Also you won't have to have a cucumber slice in your tank all the time.

they poop like crazy since they eat constantly.

They are really hardy in my experience, take a lot of abuse and stress.

Mine also like zucchini and squash I have 3 in a 10 gal, two are inseparable but often will see the 3 hanging together on the side of the tank or working over a veggie.
